Perfect gate!!! I have a 4 foot opening between my living room and dining room and was looking for something to keep the dog on one side or the other (he's an active 7 yr old 75 lb husky). This gate was easy to install and is simple, traditional and somewhat brilliant in design. There was no piece that installed into the floor - there is a piece that came attached to the bottom of the middle of the gate - this piece rests on the floor and gives the wide gate support in the middle when it's extended. It's been up for 6 months and I've never pinched a finger or anything else. I can manage to step over it but it's so easy to open and close I usually don't bother to try to go over. My dog is big - he has pushed on the gate but hasn't done any damage and the gate was sturdy enough that he has stopped trying. He did try to go over it the first day it was up. Thankfully - he didn't hurt himself or the gate - despite landing on it. It had to hurt some - he just didn't quite make it over and had to have some help getting his hind legs back on the ground. The gate wasn't phased by his 75 lb self hanging from it. I'm glad I was right there when it happened and glad it wasn't worse than it turned out... The experience was enough for him that he has not ever tried to go over the gate again. He has jumped up to put his paws on the top like he does on the fence outside - the gate is gives a little but is able to take it without any damage. And thankfully - he doesn't do this often. At first the gate was really important so that I could separate the cats who had live here for 10 years from the newly adopted 7 yr old large dog who wanted to chase them. Over time the gate was perfect for the job - the cats were visible but protected from him and gradually he grew accustomed to their existence. We were able to control his access to them and eventually train him to get comfortable and not chase them at all. I had expected to remove the gate once we reached peaceful cohabitation... but it swings out of the way so easily and has proven useful for other occassions when I want to keep the dog contained while a door is open or something - so it remains installed and helpful.
